There is no actual turn signal relay. I think you mean the turn signal flasher. This is the part that actually causes the signals to flash. It does look like a relay though. The flasher part number is(NNN) NNN-NNNNand goes for $55 from the dealer. Is this what you purchased? Please reconsider changing my rating to good or better.
#4 is the flasher in the picture above.
See below for all info regarding the turn signal system:
A chime will sound after the vehicle has traveled a distance of approximately 0.5 Mile with the turn signal ON.FLASHER MODULE DESCRIPTION The Turn Signal/Hazard Warning Flasher is a module providing the vehicle with turn signal and hazard warning functions and has been designed with internal relays to take advantage of low current switching requirements in the vehicle. It is plugged into the Junction Block at position 4, where all wiring associated with its operation is terminated. The Junction Block is adjacent to and left of the steering column of the vehicle. To gain access to the flasher, remove the lower steering column cover and knee blocker.
The ignition input to the combo-flasher will draw typically 5 mA of current while active.
